A plotter produces vector graphics drawings. Plotters draw lines on paper using a pen. In the past, plotters were used in applications such as computer-aided design, as they were able to produce line drawings much faster and of a higher quality than contemporary conventional printers, and small desktop plotters were often used for business graphics. Although they retained a niche for producing very large drawings for many years, plotters have now largely been replaced by wide-format conventional printers.
In digital printing, a page description language (PDL) is a computer language that describes the appearance of a printed page in a higher level than an actual output bitmap. An overlapping term is printer control language, which includes Hewlett-Packard's Printer Command Language (PCL). PostScript is one of the most noted page description languages. The markup language adaptation of the PDL is the page description markup language.
OpenVMS is a multi-user, multiprocessing virtual memory-based operating system (OS) designed for use in time-sharing, batch processing, and transaction processing. It was first released by Digital Equipment Corporation in 1977 as VAX/VMS for its series of VAX minicomputers. OpenVMS also runs on DEC Alpha systems and the HP Itanium-based families of computers. OpenVMS is a proprietary operating system, but source code listings are available for purchase.
The LaserWriter is a laser printer with built-in PostScript interpreter sold by Apple Computer, Inc. from 1985 to 1988. It was one of the first laser printers available to the mass market. In combination with WYSIWYG publishing software like PageMaker, that operated on top of the graphical user interface of Macintosh computers, the LaserWriter was a key component at the beginning of the desktop publishing revolution.
HP-GL, short for Hewlett-Packard Graphics Language and often written as HPGL, is a printer control language created by Hewlett-Packard (HP). HP-GL was the primary printer control language used by HP plotters. It was introduced with the plotter HP-8972 in 1977 and became a standard for almost all plotters. Hewlett-Packard's printers also usually support HP-GL/2 in addition to PCL.
In computers, a printer driver or a print processor is a piece of software on a computer that converts the data to be printed to a format that a printer can understand. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model.
NewWave is a discontinued object-oriented graphical desktop environment and office productivity tool for PCs running early versions of Microsoft Windows. It was developed by Hewlett-Packard and introduced commercially in 1988. It was used on the HP Vectras and other IBM compatible PCs running MS Windows.
LaserJet as a brand name identifies the line of laser printers marketed by the American computer company Hewlett-Packard (HP). The HP LaserJet was the world's first desktop laser printer. As of 2016, Canon supplies both mechanisms and cartridges for all HP's laser printers.
NonStop is a series of server computers introduced to market in 1976 by Tandem Computers Inc., beginning with the NonStop product line, which was followed by the Hewlett-Packard Integrity NonStop product line extension. It is currently offered by Hewlett Packard Enterprise since Hewlett-Packard Company's split in 2015. Because NonStop systems are based on an integrated hardware/software stack, HPE also developed the NonStop OS operating system for them.
The HP 2640A and other HP 264X models were block-mode "smart" and intelligent ASCII standard serial terminals produced by Hewlett-Packard using the Intel 8008 and 8080 microprocessors.
Printer Command Language, more commonly referred to as PCL, is a page description language (PDL) developed by Hewlett-Packard as a printer protocol and has become a de facto industry standard. Originally developed for early inkjet printers in 1984, PCL has been released in varying levels for thermal, matrix, and page printers. HP-GL/2 and PJL are supported by later versions of PCL.
The HP 9800 is a family of what were initially called programmable calculators and later desktop computers that were made by Hewlett-Packard, replacing their first HP 9100 calculator. It is also named "98 line". The 9830 and its successors were true computers in the modern sense of the term, complete with a powerful BASIC language interpreter.
The HP LaserJet 4 is a group of monochrome laser printers produced in the early to mid-1990s as part of the LaserJet series by Hewlett Packard (HP). The 4 series has various models, including the standard LaserJet 4 for business use, the 4L for personal use and the 4P for small businesses. Additional models included the 4Si model, created as a heavy-duty business printer, and the 4V model, a B-size printer for desktop publishing and graphic artists. There are also PostScript variants of these machines with the '4M' designation, where M stands for, but is not limited to, usage with an Apple Macintosh. Hewlett Packard also released an upgraded version of the LaserJet 4/4M known as the 4 Plus ('4+')/4M Plus ('4M+').
The LaserJet 4000 series is Hewlett-Packard's medium-duty monochrome laser printer range and the successor to the LaserJet 5 series.
The Hewlett-Packard Raster Transfer Language is a subset of the Printer Command Language (PCL) language. It is used to embed true raster images (bitmaps) into plotter files. Modern plotters are raster devices, so they need a raster-based language. For backward compatibility they also support the HP-GL/2 vector language, so the HP RTL language is designed for mixing with the HP-GL/2 language.
The Hewlett-Packard Company, or Hewlett-Packard, was an American multinational information technology company headquartered in Palo Alto, California. It developed and provided a wide variety of hardware components as well as software and related services to consumers, small- and medium-sized businesses (SMBs) and large enterprises, including customers in the government, health and education sectors. In 1999, HP split into two companies: one retaining the original company name, the other named Agilent Technologies. The first product line of Hewlett-Packard, test and measurement equipment, went to Agilent Technologies, while HP retained focus on its later products including computers and printers. In 2015, HP again was split into two separate companies, HP Inc. and Hewlett Packard Enterprise.
In computing HP Roman is a family of character sets consisting of HP Roman Extension, HP Roman-8, HP Roman-9 and several variants. Originally introduced by Hewlett-Packard around 1978, revisions and adaptations were published several times up to 1999. The 1985 revisions were later standardized as IBM codepages 1050 and 1051. Supporting many European languages, the character sets were used by various HP workstations, terminals, calculators as well as many printers, also from third-parties.
The Harlequin RIP is a raster image processor first released in 1990 under the name "ScriptWorks" running as a command-line application to render PostScript language files under Unix. It was developed by Harlequin, a software company based in Cambridge, England.
HP Universal Print Driver (UPD) is an intelligent print driver that supports a broad range of HP LaserJet printers and MFPs. Developed by Hewlett-Packard, it combines a general purpose driver and HP proprietary extensions. HP UPD simplifies driver deployment and management. This advanced print driver has the ability to discover HP printing devices and automatically configure itself to the device capabilities.
In computing, a hardware code page (HWCP) refers to a code page supported natively by a hardware device such as a display adapter or printer. The glyphs to present the characters are stored in the alphanumeric character generator's resident read-only memory and are thus not user-changeable. They are available for use by the system without having to load any font definitions into the device first. Startup messages issued by a PC's System BIOS or displayed by an operating system before initializing its own code page switching logic and font management and before switching to graphics mode are displayed in a computer's default hardware code page.
